Radioactivity

10 lives in this collection worked in radioactivity, from 1832 to today. Each has a full course on their life and the mathematics and physics they made.

Often together with: nuclear physics, physics, atomic physics, chemistry, radiochemistry. All fields

  • William Crookes1832–1919

    London chemist and physicist who discovered thallium, invented the radiometer, the Crookes tube and the spinthariscope, and also investigated spirit mediums.

    chemistry, spectroscopy, vacuum physics

  • Henri Becquerel1852–1908

    French physicist who discovered the spontaneous radioactivity of uranium in 1896 and showed that beta rays are fast electrons.

    physics, radioactivity, optics

  • Pierre Curie1859–1906

    French physicist who discovered piezoelectricity with his brother Jacques, formulated the symmetry principle and Curie's law of magnetism, and co-discovered polonium and radium with Marie Curie.

    physics, crystallography, piezoelectricity

  • Marie Curie1867–1934

    Polish-French physicist and chemist who showed that radioactivity is an atomic property, discovered polonium and radium with Pierre Curie, and was the first person awarded two Nobel Prizes.

    physics, chemistry, radioactivity

  • Ernest Rutherford1871–1937

    Experimental physicist who explained radioactivity as atomic transformation, discovered the atomic nucleus and produced the first artificial nuclear reaction.

    nuclear physics, radioactivity, atomic physics

  • Lise Meitner1878–1968

    Austrian-Swedish physicist who co-discovered protactinium with Otto Hahn and, with Otto Frisch, gave the first physical explanation of nuclear fission.

    nuclear physics, radioactivity, beta and gamma spectroscopy

  • Hans Geiger1882–1945

    Experimental physicist who counted alpha particles with Rutherford, made the scattering measurements behind the nuclear atom and invented the Geiger–Müller counter.

    nuclear physics, radioactivity, particle detection

  • Henry Moseley1887–1915

    Physicist whose X-ray spectra showed that atomic number is the charge of the nucleus and fixed the order and gaps of the periodic table.

    x-ray spectroscopy, atomic physics, radioactivity

  • James Chadwick1891–1974

    Experimental physicist who discovered the neutron, showed the beta spectrum is continuous and led the British mission to the Manhattan Project.

    nuclear physics, radioactivity

  • Irène Joliot-Curie1897–1956

    French physicist and chemist who with Frédéric Joliot discovered artificial radioactivity, and whose 1938 work with Pavle Savić on neutron-irradiated uranium helped lead to the discovery of fission.
